The condensation sequence predicts that asteroids consisting of carbonaceous material would form
a.
in the inner solar system where it is warmer.
b.
at random locations then migrating to the outer asteroid belt due to the gravitational influence of Jupiter and Saturn.
c.
in the outer solar system where it is very cold.
d.
between the orbits of Jupiter and Saturn.
e.
in the outer asteroid belt where it is cooler.
Due to the fact that planets emit more infrared radiation than any other type of light, astronomers have the best chance of directly imaging an exoplanet in the infrared part of the spectrum.
select one of the following:
A) true
B) false
On February 15, 2013, Asteroid 2012 DA14 passed within 17,200 miles [mi] of the surface of the Earth at a relative speed of 7.8 kilometers per second [km/s]. This is considerably closer than the orbit of geosynchronous satellites (26,200 miles). This is the closest recorded approach of an object this large. The asteroid 2012 DA14 was estimated to have a diameter of 30 meters [m] and a specific gravity of 3. If 2012 DA14 had hit the Earth, what is the total amount of energy that would have been released (i.e., what was the kinetic energy of the asteroid)? Express your answer in megatons [Mton]. One megaton is the energy released by one million metric tons of TNT explosive. A metric ton equals 1,000 kilograms [kg], and the explosive energy of TNT is 4,184 joules per gram [J/g].
